What makes the comet different?

  1. The comet goldfish is a great breed for those new to keeping an aquarium. They’re easy to take care of and because of a hardy nature can be kept in an outdoor pond or inside your house in an aquarium or tank.
  2. These are much smaller than the common goldfish. An average comet usually reaches 6 to 10 inches although there are certain specimens that can reach up to 12 inches.
  3. An outstanding feature of this fish is its beautiful tail. The forked tail is very long (at least 3/4 of the length of the body). In large comets where the body is about 12 inches long, the tail can be the same length, and in some circumstances it can be longer than the body.
  4. The tips of the caudal fin are clear and this is attractive, especially if it’s seen in the background of the comets color. The graceful flow is beautiful to watch.
  5. Commonly this goldfish is yellow and silver in color. However they can also come in a combination of other metallic colors.
  6. Comets are fast, agile swimmers.
  7. They are very fertile and can multiply and propagate in a short span of time. They are one of the most prolifically bred fish in pet shops.
  8. Comets also have the usual characteristics that goldfish possess.
